elf: Pass need_layout to _bfd_elf_map_sections_to_segments
On some targets, the DT_RELR section size can be computed only after all
symbols addresses can be determined. Update ldelf_map_segments to pass
need_layout to _bfd_elf_map_sections_to_segments which will size DT_RELR
section and set need_layout to true if the DT_RELR section size is changed.
bfd/
* elf-bfd.h (_bfd_elf_map_sections_to_segments): Add a bool
pointer argument.
* elf.c (_bfd_elf_map_sections_to_segments): Add a bool pointer
argument to indicate if section layout needs update.
(assign_file_positions_for_load_sections): Pass NULL to
_bfd_elf_map_sections_to_segments.
* elflink.c (_bfd_elf_strip_zero_sized_dynamic_sections): Pass
NULL to _bfd_elf_map_sections_to_segments.
ld/
* ldelfgen.c (ldelf_map_segments): Pass &need_layout to
_bfd_elf_map_sections_to_segments.
